Matt Jones' Diamond Encrusted Marin San Quentin - NEC Cycle Show 2019

Matt Jones is currently in North Wales feeling out the Hardline course, but when he gets back, he'll have this custom-painted, jewel-encrusted Marin San Quentin waiting for him. The bike is a 130mm-travel hardtail with an eye-catching space-themed color scheme and not a sticker in sight. It was painted especially for Jones, who's a self-confessed science nerd, and then he specced it with his dream parts.

What really tops this build off is the stem cap that contains real diamonds and rubies in the shape of Matt’s initials, making this easily the most expensive bike at the show.

There are apparently 26 real jewels in the solid silver cap, so they'll have to keep a close eye on it over the weekend in the NEC.

Matt Jones was part of the team that developed the San Quentin, as he was looking for a more trail-friendly version of the Alcatraz dirt jump hardtail he also helped the brand to produce. The result is a British-style long and slack hardcore hardtail with a low standover to replicate a dirt jump bike feel.

Other constellations in the Jones nebula include the Spade and the Bike Frame.

Matt's custom bike was specced with an AXS Eagle drivetrain, Cane Creek eeWings cranks, a Gusset cockpit, TRP G-Spec brakes and a Marzocchi Z1 fork. This has been called the 'dream build' edition, one that you can't buy, and probably never will be able to, but in an ideal world, this is about as plush as a Marin San Quentin is going to get. Finishing off the build are Halo's new signature Matt Jones wheels. As far as we can tell, they are the same as the regular Vortex wheel, but they're shiny and you can now get a Matt Jones sticker on them.

More info:

The paint job from Image Design Customs is simply unbelievable. So nice that we'll ignore the fact the tire is the wrong way round.

Red no more. The Marzocchi fork gets the space treatment, too.

It's the little things, like these matching purple titanium bolts, that make this build really come together.

Cane Creek eeWings cranks to help this bike liftoff. Yes, Matt has already flipped it.

Wireless SRAM AXS parts for the drivetrain.

A Gusset bar and stem keep the dirt jump feel for Matt.

 Right?! Did they forget to polish it or something? And how about the placement/kerning on the MJ initials... weak effort.

 @lognar: Didn't sound that way from the description but you're probably right. What a shame though to stick on such exotica and then lump on some cheap underperforming forks!

 Seems like the San Quentin should have the most drab. bleak, and hopeless paint job imaginable. Maybe a Living Hell edition.

 I agree... up front there ought to be a bike in black. I heard he roosted a berm in Reno just to watch it die

 Nice SQ. Love mine for downhills and jumps. Wish it was a better climber, but that is why I am getting a Hawk Hill. Going to rock the pink.

 I sprinkle diamonds on everything I ride, two reasons: one, it's the most baller shit you could possibly do to your bike and two, makes my dookie twinkle, man.

 Didn't really know who MJ was until I stumbled upon his YT channel. Even though he is sponsored by Marin and had a hand in designing the San Quentin you can tell he really loves riding this hardtail.

 Such a nice paint job! Love the fork
The frame stands out way too much for my level of riding, so id just want that fork on a black/raw DJ frame

 What exactly is it that you love about a budget fox 36? Must be the stickers!! FWIW that's what I have on my bike but only because I'm poor.

 @friendlyfoe: what's not to love about a budget 36? I realise it's no longer an Italian made marz but still a great fork and at a good price

 All that money wasted on bling, so they couldn't afford cable stops or something other than plain zip ties to hold the cables to the frame.
  • 9 1
 I understand the problem of no grommets, but cable ties are the best way to fix cables to a externally routed frame

 It might have a few incredibly tiny jewels in it, but that won't make it the most expensive bike at the whole show at all.

 why not an axis wireless dropper and just eliminate the dropper cable?

 Hes sponsored by fox, which means he cant use rockshox ????

 @Martynich94: But then again uses an "off-brand" Marzocchi fork instead of a real Fox36... Guess the sponsoring wasn't the problem for the dropper.

What I wonder more is why he didn't get a Fox36 Performance Elite. He obviously wanted black stanchions and you can't normally buy Fox Performance Elite part since they are OEM-only.

My guess is that he didn't get sponsored parts because this is a "private" project. The Marzocchi fork and the dropper are just way cheaper than a Fox36 and AXS dropper.

 @Leicester: marzocchi is owned by fox. Fox want their riders running all of their products from their brands, for the marketing value. If nobody sponsored by fox ran marzocchi, then the brand marzocchi simply would not have the marketing exposure.
